classic example was the astra that ploughed into the bck of my E90 a month ago.
he was far too close for most of the journey, i slowed down to maintain a decent gap in front of me. Still he managed to completely lose all focus, didnt pay attention, and when i slowed down for the traffic in front, he just kept going and smashed into the back of me.
his excuse "the sun was in my eyes"
to which i asked "do you think thats a reason to drive closer to me, or perhaps leave a bigger gap".
damn fool went quiet and gave me his insurance details.
plus.. them milk bottle top astra brakes, if i'd had to brake quickly, the distance he was at, he'd have stood no chance!
